The purpose of lubrication of rolling bearings is to reduce internal friction and wear of the bearings and prevent burning. Its lubrication effect is as follows.

⑴. Reduce friction and wear.

In the contact parts of the bearing rings, rolling elements and cages, metal contact is prevented and friction and wear are reduced.

⑵. Extend fatigue life.

The rolling fatigue life of the bearing is extended if the rolling contact surface is well lubricated during rotation. On the contrary, if the oil viscosity is low and the lubricating oil film thickness is not good, it will shorten.

⑶.Remove friction heat and cool down

Circular oil supply methods and other methods can use oil to dissipate heat generated by friction or heat transmitted from the outside for cooling. Prevent bearings from overheating and lubricating oil itself from aging.

⑷.Others

It also has the effect of preventing foreign matter from invading the inside of the bearing, or preventing rust and corrosion.
